SRC-2 Soil Respiration Chamber
Our SRC-2 Soil Respiration Chamber is available for use with the EGM-5
for measurement of closed system, soil CO
2
efflux. There are two gas
connections required, one to the GAS IN port, and the other to the GAS
OUT port on the EGM-5. It is constructed out of rugged PVC with a
convenient handle for placement on the soil surface. An aluminum ring
provides a good seal on the soil surface or on collars.
• Dimensions: 150 mm (Height) x 100 mm (Diameter)
• Volume: 1171 ml
• Area: 78 cm

CPY-5 Canopy Assimilation Chamber
Our CPY-5 Canopy Assimilation Chamber is available for use with the EGM-5 for measurement of closed
system, net canopy CO
2
flux. It is transparent and constructed out of rugged polycarbonate with an
aluminum ring, which provides a good seal on the soil surface or on collars. It also includes sensors for
measurement of air temperature and PAR within the chamber. There are two gas connections required,
one to the GAS IN port and the other to the GAS OUT port on the EGM-5.
